Error: Reference to non-existent field 'hessian_eq_zero'

Reference to non-existent field 'hessian_eq_zero'.    

Error in stochastic_solvers (line 56)
if M_.hessian_eq_zero && local_order~=1

Error in resol (line 144)
[dr,info] = stochastic_solvers(dr,check_flag,M,options,oo);

Error in check (line 73)
[dr,info,M,options,oo] = resol(1,M,options,oo);

Error in version7_simul_v2 (line 1133)
oo_.dr.eigval = check(M_,options_,oo_);

I am trying to run a .mod file I got from someone,
I am not sure why I am running into this problem which does not seem to occur to the person who has sent me the file.

Here is the line 56

local_order = options_.order;
if M_.hessian_eq_zero && local_order~=1
    local_order = 1;
    warning('stochastic_solvers: using order = 1 because Hessian is equal to zero');
end

Thanks for your help in advance.

Please try the most recent stable version of Dynare.

I get that error msg while using the most recent version, 4.6.3.

I first ran into this error msg
Reference to non-existent field 'set_auxiliary_variables'.
Error in evaluate_steady_state (line 49)
if length(M.aux_vars) > 0 && ~steadystate_flag && M.set_auxiliary_variables
Error in steady_ (line 55)
[steady_state,params,info] =

When I download the older version (4.5.0) I can run the code a bit further, but then stuck at another error msg (hessian).
Reference to non-existent field ‘hessian_eq_zero’.
Error in stochastic_solvers (line 56)

Not sure what is wrong…

Can you provide the mod-file in question?
